Problem by quitting yolov5s realtime on Jetson Xavier NX

[YuanqingXie]

I ran yolov5s successfully on Jetson Xavier NX with raspberry pi Camera. But after i entered "q" to quit. I got at first this message:
Traceback (most recent call last):
File "detect.py", line 174, in

548024421584 (0x7ecc001be0)
548024422880 (0x7ecc003ee0)

After that, when i ran yolov5s again, i got this message:
Traceback (most recent call last):
File "detect.py", line 174, in

File "detect.py", line 121, in detect

StopIteration

Killed

I have to enter : sudo systemctl restart nvargus-daemon, again and again. And i got no such problem if i ran on PC.
How can i solve this problem?

@YuanqingXie try CTRL+C to quit.

i got this, if i try ctrl+c, and i have to force to quit :

[glenn-jocher]

Sure, that looks fine. CTRL+C is supposed to produce a KeyboardInterrupt.

[YuanqingXie]

Yes, thanks. But when i try twice i got error and can't run it again unless i restart the jetson. how to quit it without any errors?
